Perhaps you may consider using diodes instead of resistors. I have no idea of your voltage and current requirements but 1N400x diodes are cheap and can be strung in series to give a range of voltages.
I am reminded how years ago the son of my late wife's friend wanted to drop the speed of two windscreen motors. He had tried resistors, but the regulation was poor, so I designed a switching circuit that did the job but when he saw that it incorporated a pot. which varied the speed a whole new world of possibilities opened up. It was a classic example of me, the Engineer, not asking questions of the end user at the start.
I was very good at that
